MENDOZA – Argentina have waived the rule for overseas-based players and have called on some of their 'foreign legion' to strengthen their squad for a Rugby Championship second-round match against South Africa in Mendoza this Saturday.

Argentina, who lost 34-21 to the Springboks in Durban on Saturday, have recalled a fit-again Jeronimo de la Fuente and have included Santiago Alvarez Fourcade and Santiago Carreras for the first time.

There is also a debut for hooker Facundo Bosch, who plays his rugby for Agen in France.
